HOT-AIR DISTRIBUTOR.

tion nearer the floor thus effecting more completeHutil-ization of heat from the furnace or source of sui'pply, and further by its use, resulting in a saving, of fuel consumption.

A further object of the invention is to pro-- vide, in a manner as hereinafter set forth, a hot air distributor capable of being employed, when deflecting the heat, as a foot warmer. V 7

Further objects of the invention are to provide, in a manner as hereinafter set forth, a hot air distributor which is simple in its construction and arrangement, strong, dun able, compact, thoroughly efiicient in its use, conveniently installed withrespect'to a hot air outlet, and comparatively inexpensive to manufacture.

With the foregoing and other objects in View, the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described, and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which fall within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views:

Figure l is a top plan view of a hot air distributor, in accordance with this invention, showing the adaptation thereof lIl connection with the hot air outlet of a pipeless furnace. c Figure 2 is a vertical sectional view of the distributor, showing the adaptation thereof with respect to the hot air outlet of a pipeless furnace. s a

Figure 3 is a fragmentary view, in vertical section, of modified arrangement of top plate.

Referring to the drawings indetail 1 denotes a floor, mounted on joistsfz, and provided with an opening 3. The joists pro= Ject inwardly from the wall of the opening 3 to for-In a seat 4 for a purpose to be presently referred to. Verticalsupports 5 are secured to the joists 2. i As illustrated the a opening 3 is of square contour and mounted upon the seat 4 and snugly abutting against the wall 'of -the opening a grating or register 6. The grating 6 is flush with the upper face of the floor 1.

leads from a pipeless furnace or other suit able source of hot air supply, The duct 7 is cylindrical in cross section and the diameter thereof is less than the width and breadth of the grating 6. The top edge of the duct 7 abuts against the lower face of the grating 6 and said duct 7 is disposed centrallywith respect to said grating 6. The diameter of the ducts 7, with respect to the width of the grating 6 is sueh, that when the duct 7 is positioned relatively to the grating 6, the latter will be provided with a hot air outlet portion 8 and a cold air inlet portion 9, which is arranged eXteriorl'y withrespeot to the outer periphery of the wall of the duct 7, The outer perip hery of the wall of the duct 7 is positioned a substantial distance from the end edges of the inwardly projecting portions of the joist 2.

The distributor comprises an inverted 1hollow frustro-conical body portion 10 having an inlet 11 at its lower end and its up er end closedby a flanged topplatelQ. The body portion 10 in proximity to each top edge formed with spaced ports 13.

Formed integral with the lower end of the body portionlO, as well as communicating with the inlet 11, is the upper stationarysection lief a tubular neck, and the latter further includes a lower shiftable tubular section 15 which is slidably mounted on the section 14 The section 15 has a bayonet shaped slot 16 through which extends a L in 17 carried by the lower end oft-he section 14-, The body portion 10 is a deflector.

The body portion 10 is supported in a vert-ical position, by a series of spaced legs 18 and each of which is formed with afoot 19, Each leg consists of a vertically disposed bar Qtlhaving an out-turned upper endQl whichiis fixedly seoured to the body portion A hot air ductis lndi'cated at and with a handle 28 preferably constructed of wood. a

When thedistributor is mounted in the position as shown'in Figure 2,it will serve to deflect the warm air out into the room and keep it in circulation nearer thefloor, thus effecting more complete utilization of the heat from the furnace. As the neck portion is hollow, the warm air can enter the body portion 10 in sufiicient quantity tothoroughy heat it and the distributor can then opertionto be discharged therefrom, thereby intit) suring a steady flow of heat through the body portion 10.

The tubular neck provides means for positioning the distributor with 'respectto the ggating The distributor preferably will positioned centrally with respect to the grating, as such position would obtain maximum results. The setting up of the neck with the lower shiftable section 15,-enables said section to he slid up higher than the feet of the supporting legs, enabling the user of the device to place the distributor in any desired position on the register and after so positioned, the lower section is moved downwardly to extend through an opening in the grating and which prevents the shifting of the distributor relative to the grating. Thehandlemvhich preferably is constructed of wood, insures a cool hold at all times, when it is desired to remove the device from its position on the grating. It is to be noted that the device is of compact enough construction so it can be easily removed entirely, if andwhen desired. The supporting legs are of suitable design and are placed and riveted to the body portion 10, and which insures solidity of the device when placed on the floor and insures proper equilibrium at all times. The distributor can be constructed of any suitable metallic material, polished or unpolished and can beof any desirable size.

The distributor will keep the warm air from going directly upward,,but instead cliffused more evenly throughout the room. The distributor diffuses the warm air in a substantially horizontal direction throughout the immediate room, as well as into an adjoining room and the "angle of deflection can be any desired, but preferably it is forty-five degrees.

The device can be utilized as a compact foot warmerby placing ones feet on the top plate 12, far enough from the floor, so that the cool air return draft will not interfere. Furthermore the use of the distributor will provide for. a saving in fuel consumption and also it is of asimple and steady construction and easily moved about.

In the modified form shown in Figure 3, the top plate indicated 28 is of such diameter with respect to the upper end ofthe hollow frusto-conical body portion 29 to project laterally therefrom and forms warm air deflecting portion 30. The marginal part of the top plate 28 is bentupon itseli ingo 1 upper end of the body portion 29 is surrounded by the flange 32 and the latter be form a fold 31 and a flaring flange 32.

ing positioned inwardly with respect to the bend 33, which provides the edge of the plate 28. The portion 30 aids in deflecting the warm air into the room nearer the floor. The portion 30 surrounds the upper end of the body portion 29. Otherwise than that as stated, the form illustrated in Figure 3 will be the same, as that set forth by Figures 1 and 2.

It is thought the many adyantages of a hot air distributor, in accordance with this invention, can be readilyunderstood, and

although the preferred embodiment of the invention is asillustrated and described, yet it is to be understood that changes in the details of construction can be had which will fall within the scope of the invention as claimed. i
